Thank you for you reply. I managed to generate a one-time password via the CLI, and I can successfully log in, however I need to do it for a every new session, and besides I don't have the right permissions to create a new folder or file.
OK, then it does not look like WinSCP question. Please talk to your administrator.
And if I set a master password what username shall I use to log in?
Do you mean WinSCP master password? That has nothing to do with your problem.
Thank you for your response. I used a workaround by creating a new folder in the home directory instead of root, and setting required permissions on that particular folder.
I really appreciate your help.
